How to Deal with Solvent Bumping and Foaming During Lab Evaporation

Apr 20, 2017 By controlling the speed of the pump, these devices can drastically reduce or eliminate the likelihood of bumping. KNF Neuberger’s new vacuum controller has an automatic feature that senses the vapor pressure of the solvent and uses that as a set point. This feature allows the user to optimize the speed of evaporation without bumping.

Alternative to Rotovap Distillation Rollitup

Alternative to Rotovap Distillation Rollitup

Jan 01, 2015 We then can distill the ethanol solution with a rotary evaporator with little to no heat at all, instead using vacuum. Which is why I believe it is possible to make a potent extract while preserving most if not more terpenes than many other forms of extractions widely used today. Last edited: Jan 4, 2015.

Why Rotary Evaporation Is More Efficient Than Standard Distillation

Why Rotary Evaporation Is More Efficient Than Standard Distillation

Jul 19, 2018 Rotary evaporation is often favored over standard distillation, with one of the main reasons being that you can achieve a faster evaporation rate with a rotovap setup. You might be wondering why this is the case. For an at-a-glance look, the factors that can help speed up evaporation are: Decreased pressure within the system

Short-Path Distillation vs. Rotary Evaporation - USA Lab

Short-Path Distillation vs. Rotary Evaporation - USA Lab

Jun 05, 2019 Short-path distillation involves using a heated flask to gradually increase the temperature of the extraction material that’s fed into it. As the mixture heats up, its vapors rise into a fractioning tubing with the aid of a vacuum. The vapors travel a short distance—often only a few centimeters—into the tubing before being condensed ...

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...
